Release of lactate dehydrogenase (LDH) from (a) A549 cells and (b) macrophage-differentiated THP-1 cells exposed to fucoidan-based microparticles (1.0 mg/mL), free rifabutin (RFB, 0.05 mg/mL), and free isoniazid (INH, 0.1 mg/mL). Cell culture medium (CCM) and Triton X-100 were used as negative and positive controls, respectively. The released LDH calculated was based on 100% assumed for positive control. Data represent mean ± SEM (n = 3, six replicates per experiment at each concentration). * p < 0.05 compared to CCM.
